The Pathology of Incipient Polymicrogyria

Brain and Development, 2017
To characterise the early tissue changes of post encephaloclastic polymicrogyria in the human fetus.We identified and reviewed the clinical histories and autopsy pathology of post ischemic fetal cerebral cortical injury at less than 30weeks gestational age (GA). The histology of local cortical abnormalities was examined with neuronal, glial, microglial

Diverse Genetic Causes of Polymicrogyria With Epilepsy [PDF]

open access: yesEpilepsia, 2021
OBJECTIVE: We sought to identify novel genes and to establish the contribution of known genes in a large cohort of patients with nonsyndromic sporadic polymicrogyria and epilepsy.

Bilateral Symmetrical Frontoparietal Polymicrogyria

European Journal of Paediatric Neurology, 2002
A patient with bilateral symmetrical frontoparietal polymicrogyria is reported. Severe developmental delay, mental retardation, spastic tetraplegia, and seizures were the main clinical features. Magnetic resonance imaging revealed bilateral thick cortex with irregular gyri and festoon-like grey-white matter junction in the frontoparietal areas ...

De novo mutations in GRIN1 cause extensive bilateral polymicrogyria [PDF]

open access: yesBrain, 2018
Polymicrogyria is a malformation of cortical development. The aetiology of polymicrogyria remains poorly understood. Using whole-exome sequencing we found de novo heterozygous missense GRIN1 mutations in 2 of 57 parent-offspring trios with polymicrogyria.

Polymicrogyria With Dysmorphic Basal Ganglia? Think Tubulin! [PDF]

open access: yesClinical Genetics, 2014
Dominant mutations in TUBB2B have been reported in patients with polymicrogyria. We further explore the phenotype associated with mutations in TUBB2B.

Bilateral Frontoparietal Polymicrogyria

The Indian Journal of Pediatrics, 2014
Two male siblings, aged 4.5 and 10 y respectively, of a nonconsanguinous family, presented with delayed milestones and epilepsy. The older sibling had frequent seizures since 7 y of age. Seizures were generalized-tonic-clonic and were poorly controlled on valproate, phenytoin and clobazam.

Management of the Child With Polymicrogyria

Journal of Neuroscience Nursing, 2009
Polymicrogyria is one of several neuronal migrational defects. This disorder is derived from a malformation in cortical development characterized by many small gyri, shallow sulci, and abnormal cortical layering. The potential causes of polymicrogyria include genetic disorders, intrauterine cytomegalovirus infection, and fetal vascular supply ...

Bilateral opercular polymicrogyria

Annals of Neurology, 1989
Abstract Foix‐Chavany‐Marie syndrome (FCMS), or faciopharyngoglossomasticatory diplegia, is an uncommon syndrome that can result from vascular or developmental lesions of the anterior opercula bilaterally. We report the first pathological documentation of the developmental form of this disorder.
